Eism's xi, ts nos Mvimmovsd sir valve mmh ises a mrticuiar assembly of constituent parts, hereinafter fully (inscribed, and is capable of general application, but I have illustrated the preferred app1i= cation of the same; and shall hereinafter so describe it, asincorporated with the sparksplug 9 structure forming part of an internal combus: tion engine, the air admitted byrthe valve in such structure to be mixed with thefuel ad: mitted by the usual oarburetor construction, withuresults hereinbefore mentioned as the oh: .5 jscts of the invention. v

Referring to the annexed drawing; in which the sam parts are designated by the same re- Snflo ive ordingils in the several views, spark plug members 1 and 2 are assembled and inter-, 1 epnneoted inform a conventional chambered snark-plu nasing provided with the standard porcelain unit :3 longitudinally intersected by theoonduotor rod 4 having the upper binding post portion 5 and the lower electrode 6. The 51 pl casing msmber 1 and the lower part of the por elain unit are spaced to provide a chamber 7, mainly shown in Figure 1. I mount improv d air valvs in the wall of the casing member 1 and in a suitable manner necessary 9; to ffect the valve operation and the results her inaft r des ribed. manner in which I h vs incorp rated the valv as shown in the soo mnanyin drawin is as Iollows. The .outer fame of the oasing member 1 is formed with a 41 hol 8 whos por pherai wall is threaded tore: chive tubular valv supnortil haying a trans: verse groove 10 in itsouter face by means of which t may be secured in the casing member 1 t rou hth rhod um of .a suitable tool so- Qn stih with the roove 10, this particular construction also providing for properly seating the valve, h rsinsftsr fully described. al .suhno t is o irre ular tubular nonstruc: ti n, th jontor sndi n r walls -12 and .14, resn otively, boundin its o smbter 22,. being of; ma rially dif sr m; 'nrnei rs and connected by an interm ia e diagonal wall 13 to form the hamber 2:2 of th de n plai ly shown in Fi ure -:;3 which is adapted t re eiv vthe ime m wed air valve, he latt r b in a unitary strucure consi tin of hree port ons 16; .17 and 18. plain shown in th ao omoanving drawing.

A port 23 is provided which affords communication between the valve support chamber 22 and the plug-casing chamber '7, this port 23 being formed in a partition wall 26 formed in the casing member 1. When the valve is in its open position, the bottom 24 thereof is seated upon the outer face 15 of partition wall 26, but when the valve is in its closed position, said valve face 24 is spaced from the wall face 15, as indicated by the ordinal 11, Figure 3. This face 15 of wall 26 constitutes a stop limiting the opening movement of the valve. Although the valve is seated upon the face 15 of the partition wall 26, when in its open position, I provide for open entry of the air to the chamber 7 by forming the inner end of the valve with a transverse channel 25 communicating at its ends with the space 21 surrounding the valve portion 16 and communicating intermediate its ends with the port 23, as plainly shown in Figures 3 and 5. I

The elements hereinbefore described are relatively proportioned and spaced to insure a valve operation accomplishing the desired results. For purposes of illustration, I will state that one effective arrangement and proportioning consists in providing a valve throw of 1/64", i. e., the space 11 is 1/64 wide; in forming the port 23 of 1/16" diameter, in providing a clearance of .015 for the space 19 between the valve portion 18 and the support 9; in providing a clearance of .007 for the space 21; and in providing a, comparatively large vent area 20, possibly 1/64 for the space between the valve portion 17 and the valve support 9.

The operation of my improved air valve in the spark-plug structure is as follows. The downward stroke of the engine piston creates a V vacuum and suction which opens this improved air valve and permits air to enter the casing chamber 7 in the manner plainly shown in Figures 4 and 5. This air strikes the porcelain unit 3 and is broken up by said unit, the air being distributedall around the unit, and at the 45 same time the action of the air maintains the unit clean and cool. This air is drawn into the cylinder where it is thoroughly mixed with the fuel drawn from the carburetor through the cylinder inlet valve, resulting in a comparatively lean but very effective mixture of 'gas and air. This combination results in a very satisfactory combustion, giving the engine'increased power with a minimum gas consumption. The upward stroke of the piston closes the air valve, resulting in a maximum compression and the reduction of the mixture to a perfect state for combustion.

-Theiresults hereinbeforementioned are obtained by the construction and operation described, the comparatively large seating area of the valve, together with the other described features, resulting in perfect operation of the air valve over a long period of time without inducing any leakage or otherdifiiculties enticularly evident in valves of this character of the ball-valve type, the suctionapparently preventing efiicient seating of the valve when it should be closed, due to various causes such as the bouncing'action of the valve, the lack of 75. proper guiding, and the limited seat are'a which is continuously changing. I

It is evident that a suitable tool cooperating with the groove 10 will provide through the support 9 for a proper adjustment of the air valve to its seat 15 upon the partition wall 26. Also, the portion 17 of the air valve can be ground into its seat 13 in the valve support 9 by rotating the valve by means of a suitable tool adapted to engage the transverse channel 25 formed in the end of the valve portion 16. The outer portion 18 of the air valve projects somewhat beyond the face of the valve support 9 so as to permit the inspection of the valve operation from the outside of the spark-plug. This construction also permits the valve to be held open by pressing against the outwardly projecting end, whereby the valve seat and channels can be cleaned by blowing hot gases therethrough and whereby the valve can be tested. Also, by means of this projecting valve end, the valve can be agitated to start its operation if it shows a tendency to stick.

Although as perfect a mixture of gas and air cannot be obtained from the carburetor alone, as with'the combination thereof with my improved air valve, still much of the fuel adjustment. for different running requirements can be obtained by adjusting the carburetor instead of adjusting my improved air valve which cooperates therewith.

What I claim is:

1. An improved assembly for air valves comprising a chambered body formed with a hole in its outer face, a tubular valve support mounted in said hole, a perforated partition Wall between the chamber of said body and the interior of said valve support, the exterior surface of said partition wall forming a valve stop, a freely reciprocatable valve disposed in said support and formed with longitudinal peripheral portions spaced from the walls of said support and a peripheral portion adapted in one position of said valve to be spaced from the walls of said support and in another position of said valve to be seated upon one of said walls, one of said longitudinal peripheral portions extending outside of said support and means affording communication between the perforation of said partition wall and the space surrounding said longitudinal peripheral portions of said valve.

2. An improved assembly for air valves comprising a chambered body formed with a hole in its outer face, a tubular valve support mounted in said hole, a perforated partition wall between the chamber of said body and the interior of said valve support, the exterior surface of said partition wall forming a valve stop, a reciprocating valve disposed in said support and formed with longitudinal peripheral portions spaced from the walls of said support and a peripheral portion adapted in one position of said valve to be spaced from the walls of said support and in another position of said valve to be seated upon one of said support walls, and means affording communication between the perforation of said partition wall and the space surrounding said longitudinal peripheral portions of said valve, said support being adjustable toward and from said partition wall.

3. An improved assembly for air valves comprising a chambered body formed with a hole in its outer face, a tubular valve support mounted in said hole, said body having a perforated partition wall affording communication between its chamber and the interior of said valve support, the exterior surface of said partition wall forming" a valve stop, a freely reciprocatable ezaaso valve disposed in said support and formed with end longitudinal peripheral portions spaced from the walls of said support and an intermediate connecting diagonal surface portion adapted in one position of said valve to be spaced from 4. A valve comprising a cage adapted to be fitted adjustably in an apertured body and a valve member freely reciprocatable within said cage, said cage and valve member having corresponding loosely fitting end guide portions and corresponding intermediate seat portions closely contacting in the closed position of the valve, the outer guide portions differing in cross sectional area from the inner guide portions, and the clearance between the corresponding guide portions being smaller for the guide portions having the larger cross sectional area.
